Abstract:
According to an embodiment of the present invention, a method for fabricating semiconductor device includes the steps of: forming a semiconductor layer on a substrate; removing part of the semiconductor layer and part of the substrate to form a trench; forming a liner in the trench; removing part of the liner to form a spacer adjacent to two sides of the trench; and forming a bit line structure in the trench.
